A central theme is how rarely we need for people to act upon unabashedly moral motives. For most purposes cold calculations of self-interest, in some suitably extended sense, are all that is really needed to induce people to behave as morality would require. Reciprocity - the threat that others will do as they are done by - will often suffice to make people behave fairly. Uncertainty - the prospect of soon finding yourself in the position of the other - is often enough to induce people to weigh impartially the interests of all. However, there inevitably remains a subset of frightfully vulnerable people whom others have no self-interested reasons not to exploit. To secure decent treatment for them, we must appeal directly and exclusively to people's sense of morality.
Robert Goodin explores these themes through the imaginative use of anecdotes and examples in a way that will make this book a treasury of political wisdom for academics, policymakers and citizens alike. Less
